The overarching unit has students learn about, design, and build biosuits - suits designed to protect people in potentially dangerous conditions while allowing for complex tasks to still be completed. This review focuses on lessons 3 and 4 of that two-week unit (comprised of 10, 50-minute lessons). These two lessons focus on examining design constraints for particular tasks given to teams of students, then conducting materials research based on those design constraints and planning for budgetary constraints.
The materials required to implement the lessons are generally things teachers would have on hand at home or in the classroom, or could ask students to bring to school (like a snorkel or kitchen gloves).
